I drive a big truck, front bumper is about chest high, wouldn't worry much about vehicle damage. You would have to stop though. You never know who you just hit, they are still a person. Some of those guys have real tough stories, and some are just shit. When I used to have my business in downtown I talked to a lot of them. I had a few that I would let help out around the bar for a few bucks here and a few bucks there. You start to see the person through the crap after a while, and you feel bad for them...
But then one of them will get froggy and beg you to go upside their head with the Desert Eagle...
